This is likely part of the cleanup on the BDM side or in the caching.
There are some other issues related to this, like failed attach never
cleaning up on the compute side.

Title:
  Volume "in-use" although VM doesn't exist

Status in Cinder:
  Invalid
Status in OpenStack Compute (Nova):
  New

Bug description:
  Setup:

  devstack on master using default settings.

  Steps:

    1) Using tempest/stress with patch https://review.openstack.org/#/c/36652/:
    cd /opt/stack/tempest/tempest/stress
    ./run_stress.py etc/volume-assign-delete-test.json -d 60
    2) Test will do the following work flow:
         - create a volume
         - create a VM
         - attach volume to VM
         - delete VM
         - delete volume

  Problem:

  Deletion of volume causes problem, since the state is still "in-use"
  even the VM is already deleted:
